cds-question@unistra.frgalaxiescatalogsradio-galaxiesh-i-line-emissionsurveysThe Arecibo L-band Feed Array Zone of Avoidance (ALFAZOA) Shallow Survey is a blind H I survey of the extragalactic sky behind the northern Milky Way conducted with the ALFA receiver on the 305 m Arecibo Radio Telescope. ALFAZOA Shallow covered 900 square degrees at full sensitivity from 30{deg}=<l=<75{deg} and |b|=<10{deg} and an additional 460 square degrees at limited sensitivity at latitudes up to 20{deg}. It has an rms sensitivity of 5-7 mJy and a velocity resolution of 9-20.6 km/s, and detected 403 galaxies out to a recessional velocity of 12000 km/s, with an angular resolution of 3.4' and a positional accuracy between 0.2' and 1.7'. The survey is complete above an integrated line flux of F_HI_=2.0 Jy km/s for half the survey, and above F_HI_= 2.8 Jy km/s for the other half. Of the ALFAZOA H I detections, 43% have at least one possible optical/near-infrared counterpart in the literature, and an additional 16% have counterparts that only included previous H I measurements. There are fewer counterparts in regions of high extinction and for galaxies with lower H I mass. Comparing the results of the survey to the predictions of Erdogdu et al. (2006MNRAS.373...45E), and using their nomenclature, ALFAZOA confirms the position and extent in the ZOA of the C7, C{zeta}, Pegasus, Corona Borealis, and Delphinus structures, but not of the Cygnus void. Two new structures are identified, both connected to the C7 overdensity; one extends to 35{deg}, and the other crosses the ZOA.2019AJ....158..234Shttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/158/234CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/AJ/129/220 : HI Parkes Zone of Avoidance Survey (Donley+, 2005)J/A+A/505/29 : HI observations of 2MASS galaxies in ZoA (van Driel+, 2009)J/AJ/139/2130 : ALFA-ZOA precursor observation (Henning+, 2010)J/MNRAS/443/41 : Deep NIR photometry of HI galaxies in ZoA (Williams+, 2014)J/AJ/151/52 : The HIZOA-S survey (Staveley-Smith+, 2016)J/MNRAS/457/2366 : Southern ZOA galaxies 21cm HI-line (Said+, 2016)J/MNRAS/482/5167 : The 2M-ZoA galaxy catalogue (Schroder+, 2019)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/158/234https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/158/234http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/158/234https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/158/234https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/158/234http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/158/234GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AJ/158/234/table2 (Properties of ALFAZOA galaxies)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/158/234/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/158/234/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/158/234/table2?GETtext/xml+votable180.050000true262.057.416670.005555555555555556Cone search capability for table J/AJ/158/234/table3 (Possible ALFAZOA counterparts)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/158/234/table3?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/158/234/table3?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/158/234/table3?GETtext/xml+votable180.050000true262.01437.42790.0055555555555555565/7631 8050-8051 6/12448 12450 12461 12805 12807 12811-12813 12816-12817 12827 12832 12835 12839 12843 12846 12849 12851-12852 12854 12894 12903 12909 12914 12917 12919 12922-12923 12927 12930 12932 12967 12969 12972 12978 12981 12986 12994 12998 13005 13021 13028 13036 13044 13053-13056 13059 13067 13080 13082 13086 13088 13092 13094-13095 13097 13101 13106 13108 13115 13135 13142 13162 13172 13184 13186-13187 13202 13206 13209 13214 13224-13225 13229-13230 13240-13241 13243 13252 13255 13832 13862 13954 14336 14338 14344-14345 14348-14349 14352 14354 14357 14370-14372 14374 14378 14398 14404-14405 14411 14416 14420 14422 14426 14430 14432-14433 14435 14443 14448 14450-14451 14463 14470 14472-14473 14475 14478-14479 14489 14492 14497 14509 14515 14522 14525 14539 14541 14543 14552 14554 14560 14563 14575 14580 14593 14600-14601 14605 14628 14630 14656 14853 14855 14866 14876 14920 30104 30113 30118 30120 30124 30131 30134-30135 30143 30199 30203 30294 30298 30331 30371 30374 30383-30384 30386 30388 30391 30413 30434 30446-30447 30473 30485 30499 30516-30517 30529 30537 30544 30548-30550 30561-30562 30569 30571-30572 30575 30578 30580 30583 30585 30587 30600 30604 30608-30609 30613 30619 30633 30638 30647 30652-30653 30655 30657 30659 30661 30663 30665 30668-30669 30672 30675 30677-30678 30681 30686 30688 30691-30694 30696 30699 30703-30704 30706 30708 30713 31095 31191 31744 31755 31758 31769 31777 31795 31798 31800-31801 31816 31829 31833-31834 31836-31837 31847 31860-31862 31864-31865 31867-31868 31870 31874 31879-31882 31953 31956-31957 31965 32002 32010 32014 32016-32017 32019 32025 32036-32037 32048-32049 32051 32054 32057 32069 32087 32090-32091 32094 32103 32105 32107 32113 32116 32121 32123 32125-32130 32150-32151 32192-32193 32195 32210 32213 32215 32217 32220-32221 32223 32228-32229 32231 32240-32241 32244 32246 32248 32251-32252 32254https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AJ/158/234?format=asciiRadiodefaultJ/AJ/158/234/table2Properties of ALFAZOA galaxiesrecnoRecord number assigned by the VizieR team.
